Teether for wrist

My LO is 3 months and it looks like she is already feeling the pain of teething. She can't deliberately pick up an object to chew on yet, and she finds it difficult to keep hold of something that I give to her. I was thinking that if she had a teething toy attached to her wrist, she would be able to lift that to her mouth. However I cannot find such a thing anywhere. Has anyone come across such a thing?
